Respiration Flashcards
What does Respiration Release?
Energy
Word Equation for Aerobic Respiration
Glucose + Oxygen—> Carbon Dioxide + Water + Energy
Word Equation For Anerobic Respiration in MUSCLES
Glucose—-> Lactic Acid + Energy
Difference between Aerobic and Anerobic
Anerobic doesn’t use oxygen
Aerobic Does
Which Respiration is Faster?
Anerobic
Which Respiration Releases More Energy?
Aerobic
What does Anerobic Respiration Produce in Yeast
Alcohol/Ethanol
Word Equation for Anerobic Respiration in Yeast
Glucose—> Carbon Dioxide + Ethanol + energy
Method of Experiment of Anerobic Respiration in Yeast
1) Boil a solution of Alcohol
2) Cool the glucose before adding yeast cells
3) Add a layer of oil to glucose containing yeast
Why is Glucose Boiled
To remove oxygen
Kill Bacteria
Why is glucose cooled before adding yeast cells
It can kill the yeast cells if it is too hot
Why is a layer of Oil Added?
So it doesn’t react with oxygen
Changes Observed from the Anerobic respiration in Yeast Practical
Limewater turns milky
bubbles
heat produces
Where is the Respiratory System in Human
Chest
What is the chest surrounded by?
Intercostal Muscle
What is below intercostal muscle
Diaphragm
What happens to the air as it passes through the nasal cavity?
1) It is Warmed
2) It is Filtered
How are lungs adapted?
1)Large Surface Area
2)Thin
3) Moist
4)permeable
5) A good blood supply
6) A good Diffusion Gradient
Explain why the lungs have large surface area?
Each lung has many small air sacs called alveoli, which provide a large surface area for gas exchange, helping humans breathe efficiently.
Explain the Lung’s Permeable Surfaces
Oxygen and Carbon Dioxide can pass through the walls of Alveolus easily
Explain the Lung’s good diffusion gradient
Maintained by blood supply and constant breathing in and out
Explain the Lungs Good Blood Supply
Capillaries around alveoli help oxygen get into the bloodstream and take carbon dioxide back to the lungs for breathing out, keeping our body supplied with oxygen and removing waste gas.
Explain the Lung’s Moisture
Oxygen dissolves in the liquid before diffusing across the wall of alveolus . this helps increase the rate of diffusion
Define Breathing Rate
is the number of breaths per minute
Define Recovery Rate
is the time taken for your breathing rate to normal
Is there a link between the levels of fitness and breathing rate
The Fitter you are the less you need to breath as your lungs take in more air when inhaling
Is there a link between levels of fitness and recovery time?
The fitter person has a shorter recovery time
The fit persons heart pumps more blood in one pump, so it is faster to return to normal
If a student becomes fitter over time how would this affect his/her recover time?
The recovery time would become shorter
Explain Respiration During Exercise
Exercise increases muscle contraction and energy demand.
Cells carry out more respiration, requiring more oxygen and producing more carbon dioxide.
Muscles extract more oxygen from the blood and release more carbon dioxide into it.
Breathing becomes deeper and faster to replenish oxygen and remove carbon dioxide, enhancing gas exchange in the lungs.
Define Respiration
The release of energy from food
